This file allows employers to send an electronic funds transfer (EFT) for the full amount of payment along with the information necessary to identify the amount that is credited to each individual employee. Please review the LOI Release Document for information regarding the required Letter of Intent.

The Wisconsin WT-6 form serves as a withholding tax deposit report for employers who have an electronic filing waiver. This voucher is essential for reporting income tax withheld from employees' wages when filing frequency is quarterly or monthly.

Use of the personalized Form WT-6 voucher below will ensure that your withholding tax payments will be posted timely and to the correct account. Do not print a blank voucher to complete by hand.

Quarterly, monthly, and semi-monthly filers with an active Wisconsin withholding account must file an electronic deposit report (Form WT-6) even if no tax is withheld during the period covered.
